' Specicationrformng part of Letters Patent o. llgj, dated December 5, 1865:'

ence beinghad to the accmpanying drawings,

and to the letters ot' reference marked thereon.

ln 'the annexed drawings making part of this specification A represents a steam box or eylindertlwhich is made perfectly tight, except where itis designed for the steam to escape.

D represents a partition in this box or cylinder 'which is fitted 'in so as to completely separate the steam ir'oneside from that in the other.

At one end of this box or cylinder is a steamehest, B, through which steam is admitted to the box A. C represents a shaft, which passes from one end ct' the box or cylinder A tothe other, having suitable bearings at each end. The 'end ot' the shaft next to the steam-chest passes into said chest for a short distance, as is represented, though thisis not absolutely necessary.

Upon the shaft C, and firmly secured to it, are two steamwheels, E and E, which are constructed both alike. These wheels are pro ridedvcn each face with plates a a, which prevent an escape of'steam from them, except in the avenue desired.

The internal arrangement ot' the wheels is shown in Figur-'e 2. It will there be seen that a steam-passage commences at the center of each and passes in the form shown tothe periphery, where the' steam escapes i'romthe wheel. The steam passes from the boiler through proper pipes to theAstehm-chest B, and from v said chest into the shaft C, whichis made hollow as far as the center of wheel E. It escapes from shaft at the center of this wheel into the steam-passage e, and thence out at the periphery or the wheel into the lirst chamherf cr division of the box A. From this chamber it escapes into a hole, fr, which is made in the shaft C, .and thence through the sha-ttt), which is made hollow to the center of wheel E. It

passes into the wheel E at its center and out of it through the passage e into the secondv chamber or division of the box A. From this chamber the steam passes to the open air or steam passes from the wheel E into the 'said f division it acts against the expanded but partlycompressed steam and produces a betler'ef feet than were it to act simply against theopen air.

l' may use' a boxorcylinderA with nicise-f one partition, making several dvisions,'ano` thus using more than two Wheels upon the shaft C.

I propose to use the steam until its power is exhausted, havinga sufcient'n umher ot' wheels to accomplish this.

I do not propose to conine myself to the usel of steam,as l may use air to be forced into the engine in any ofthe known Ways.

The steam or air, rushing out through the passages 6, reacts upon the wheels and gives them a rotar motion.

It will be seen that when the steam is used over and overagain that all the power that can be derived from itin this way will be imparted to the shaft U.

Having thus fullydescribed my invention,

' what I claim as ne-w, and desire tosecure" by Letters Patent, is l The arrangement of the shaft, U andthe wheelsEE with the box or cylinder A, said. cylinder being provided with one or more partitions, whereby Vtwo or more chambers 'are formed in which the steam from the wheels is used more than once against partialiy-compressed steam, as and for the purpose herein specified.
